头颈部超声联合CTA对颈动脉和颅内动脉狭窄的诊断价值OA

Objective To investigate the diagnostic value of head and neck ultrasound combined with CT angiography(CTA)for carotid and intracranial artery stenosis.Methods The clinical data of 90 patients with carotid and intracranial artery stenosis admitted to Xinxiang Second People's Hospital from August 2023 to April 2024 were retrospectively analyzed.All patients underwent head and neck ultrasound,CTA,and digital subtraction angiography(DSA)examinations sequentially within 72 hours of admission.Taking DSA results as the gold standard,the consistency analysis was performed,and the diagnostic value of head and neck ultrasound,CTA,and their combination for carotid and intracranial artery stenosis was evaluated.Results DSA examination results showed that among the 90 patients,there were 39 cases of mild stenosis,33 cases of moderate stenosis,and 18 cases of severe stenosis/occlusion of the carotid and intracranial arteries.Taking DSA results as the gold standard,the Kappa values of head and neck ultrasound for mild,moderate,and severe stenosis/occlusion were 0.539,0.370,and 0.621,respectively;those of CTA were 0.768,0.590,and 0.722,respectively;and those of head and neck ultrasound combined with CTA were 0.909,0.836,and 0.894,respectively.The combined examination demonstrated the optimal diagnostic consistency for all grades of stenosis.Compared with single examination,head and neck ultrasound combined with CTA showed higher sensitivity,specificity and accuracy for mild and moderate stenosis,with better diagnostic efficacy(P<0.05).Conclusions Head and neck ultrasound,as well as CTA have certain diagnostic value for carotid and intracranial arterial stenosis.Their combination achieves complementary advantages and further improves diagnostic accuracy and reliability.
